TBH I think albums on Google Play are United States only, not available in the UK. I'm sure there's plenty of legal paid music download services that do operate in the UK, usually around 79p GBP a song, e.g. Amazon.co.uk and Apple's iTunes Store. I'm sure it's always direct download of songs and albums, not torrent.

Hi, yes I am in UK and we do have Google Music, Movies and Magazines since a while now

I just don't know if once I paid for an album or a song this will be available for download in MP3 format so I can play it on all device I want or if I can play it only from my Google device without being able to have the .mp3 file!
